What differences did you observe in the structure of an artery and vein of the umbilical cord?
Arteries have a smaller lumen (centre passage) than veins do, they also have thicker more 'muscular' walls than veins do. This is because blood pressure is higher in arteries than in veins, as arteries carry blood away from the heart, veins carry blood to the heart, pressure has to be high in arteries so that blood can reach all around the body.
What is the difference between an umbilical vein and umbilical artery?
veins carry blood back to the heart, while arteries carry blood away/from the heart. therefore, the arteries carried the oxygen from the heart to the baby via umbilical artery, and the veins picked up waste products such as carbon dioxide and carried it back to the heart via the umbilical vein.

What happens in your veins?
Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. In contrast to veins, arteries carry blood away from the heart. Veins are less muscular than arteries and are often closer to the skin.
What are the arteries and veins called that service the kidneys of a frog?
Renal arteries and veins service an animal's kidneys.
Is the oxygenated blood found in the umbilical vein or in the umbilical arteries?
arteries
What is it called when arteries and veins are together?
Capillaries
Why are some blood vessles called arteries?
yes there are arteries, veins, and capilaries
Do arteries carry oxygenated blood to the heart?
Oxygen All arteries, except the pulmonary and umbilical arteries, carry oxygen. None of them carry carbon dioxide.
What are the blood vessels leading away from the heart called?
Arteries. Because the capilaries connect the arteries to the vein as Veins carries blood back to the heart.
